my goal here was to make a sampler that plays back samples of an instrument while playing an instrument. that way, i can have a “autotune” for my bad trumpet playing - e.g. turning off the monitor and sequencing with the notes i’m trying to play.
add crow support
midi input (optional, use built-in harmonizer instead)
K2 arms recording
K3 forces recording
K1+K2 toggles monitor
E1 activates presets
E2/E3 trims sample
sampling: plug in midi keyboard and audio source. turn E1 to “sampler”. press K2 to arm or K3 to directly record. then play audio. now you can play it back on your midi source.
random harmony: turn E1 to “follower”. change harmonizer -> probability to 100%. change the scale and root note to your preference. then press K2 to arm and play a sound through the input…
there are a number of customizable parameters in the global menu. currently there are two presets (E1 toggles):
“sampler”: generic sampler. record once and then midi notes are shifted by a constant amount (relative to middle c).
“follower”: sample in realtime. playing midi during recording will try to play notes near the leading edge, using a realtime pitch-detector to correctly pitch shift.
i’m sure there are other interesting combos. here is a quick rundown of some parameters:
recording->rec thresh: lower to more easily trigger recording when armed
recording->silence to stop: recording after armed stops after this much silence
playback->min recorded: is the amount recorded before note playback is possible
playback->playback reference: determines how pitch adjustment works
playback->live follow: starts notes behind the latest sample
playback->keep armed: re-arms recording if recorded stops
playback->only play during rec: sequenced notes only emit during recording
playback->midi during rec: use to disable midi during recording
playback->notes start at 0: start notes at 0 or from where they last were
i think there is potential for cool weird vocal effects with this. haven’t explored that yet.
here’s one more demo showing the “sampler” mode (the second preset of the current two presets). “sampler” mode behaves like a classic sampler. pitch-shifting is relative to middle-c (although you can change pitch detection to “median” to automatically pitch it if its a single note). sample one note and then play the sample after recording and tweak the start/end points.
@SPIKE yeah i realized that this script requires a little more kung fu than my others. let me see if i can get you out on the road
the waveform is normally grayed out (my videos had boosted contrast), so when you play a note you should see your note travel through the waveform in a bright pattern.
on the op-1 the midi is weird, and seems to work (for me) only after going out of synth mode and then back into synth mode. can you try that if you’re using the op-1 midi?
if you are in “sampler” mode the midi during recording is turned off. if you aren’t in any mode, double check the midi during rec and make sure it is yes. also check that only play during rec is no. this should make sure you get midi emission no matter what.
since you have an op-1 an easy test is to do the following. plug in the audio and midi from op-1 into norns. record one bar on the op-1 with a note from any engine. have that play indefinetly. switch to a synth (like pulse) where you can turn the volume all the way off. now you should be able to play the midi (with only audio from your pre-recorded material) and the midi should activate the samples.
hmu if its still troublesome.
i’ve noticed its a bit sensitive on the norns shield to get it to move one space between modes. i could hook it up to something like K1+K3 instead to switch modes too.
make sure your device is set to number 1. goto system -> midi and then select your midi device. i’d suggest trying “sampler” mode (turn E1). sample something and then see if pressing a key on your midi device activates the sample. if you can open maiden and watch the output you should see something happening when you press a midi key. lmk if you still have issues.
